Katherine wants to investigate if the time of day a plant is watered affects the growth of the plant. She hypothesizes that a pl

ant watered in the morning will grow faster than a plant watered at other times of the day.. . Identify the specific independent and dependent variables that will be involved in an experiment to test this hypothesis.. . List at least five variables that should be controlled during the experiment. For each variable identified, give a specific suggestion for how it can be controlled during the experiment.

 <span>Independent variable: Time plants are watered (ex. 8am, 12pm, 4pm, 8pm, 12am) 
Dependent variable: growth of the plant 
Controlled variable: 1. same type plants, 2. same amount of sunlight, 3. same type of dirt, 4. same type of water, 5. same amount of water (each are self explanatory of how to control)</span>

The controlled release of nuclear energy in a reactor is accomplished by
zhenek [66]

Nuclear power refers to the application of nuclear reactions, which discharge nuclear energy to produce heat and is most generally utilized in steam turbines to generate electricity in a nuclear power plant. Nuclear energy can be obtained from nuclear decay, nuclear fission, and nuclear fusion reactions.  

The controlled release of nuclear energy in a reactor is attained by controlling the fission without controlling a chain reaction. If a chain reaction occurs, then the amount of energy would increase exponentially, so in order to monitor the release of energy, fission must be controlled without controlling a chain reaction.

What is true of macroevolution?
Allisa [31]

Answer:

b. It is evolution above the species level.

Explanation:

Macroevolution is the evolution that generates new taxa, for examples two or more species from a common ancestor. Macroevolution is the product of microevolutionary processes, it is, of <u>microevolution</u>: the change in allele frequencies in a population over time.  Macroevolutive changes are commonly evident while not all microevlutive changes are not.

the diagram below represents two cells, x and y which statement is correct concerning the structure labeled A ?
DaniilM [7]

The diagram below (attached image) represents two cells, X and Y.

Which statement is correct concerning the structure labeled A?

A) It is involved in cell communication in cell X but not in cell y.

B) It represents a cell wall in cell X and the cell membrane in cell y.

C) It prevents the absorption of CO2 in cell x and O2 and cell y.

D) It aids in the removal of metabolic waste in both cell X and Y ​

Cell membrane accomplishes several functions, among them, the removal of cell wastes. Option D. It aids in the removal of metabolic waste in both cell X and Y.

<h3>What is the cell membrane?</h3>

The cell membrane is a barrier that surrounds the cell content and isolates it from the extracellular space. It is composed of two lipidic layers, proteins, and glucans incrusted in between.

The cell membrane accomplishes many different functions. Among them, we can mention,

  • Isolation ⇒ It separates the intracellular content from the extracellular space.

  • Protection ⇒ It protects the interior of the cell from any damaging external factor that might affect its correct functioning.

  • Transport ⇒ It allows the selective pass of certain molecules or ions.

Substances interchange

⇒  Passive transport → Simple diffusion → through lipids

                                     → Facilitated diffusion → Assisted by channel  

                                        proteins

                                     → Does not need energy

                                    → Depends on the molecule size, the concentration                      

                                       at each side of the membrane, and the charge of      

                                       the ions.

                                      → Occurs in favor of the electrochemical gradient

⇒ Active transport → It does the energy to occur

                                → Mediated by carrier proteins

                                → Transport big-sized molecules

                                → Against the electrochemical gradient

⇒ Endocytosis/Exocytosis → Active transport mediated by vesicles.  

  • Communication ⇒ By emission and reception of substances and molecules, the cell can communicate with other cells. This process is always mediated by membranes and their transport proteins or receptor proteins.

In the exposed example X cell represents an animal cell, and Y cell is a plant cell.

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

Among the options, the correct one is D. It aids in the removal of metabolic waste in both cell X and Y
